A lot of western instrumentation and test equipment used to come with full circuit diagrams and assembly info. The understanding was that your HP spectrum analyser or Tektronix scope cost so much money that if it broke then you would have it repaired, and to do the repair you need the circuit diagram.
- dom0 9y agoNot any more, of course. It also deserves to be mentioned that lots of higher-end equipment used a lot of custom parts, and not always out of necessity (like custom µPs in HP multimeters, or stuffing solenoid drivers into unrelated hybrids ... and of course anything handling higher frequencies almost always used some custom chips or selected transistors hidden behind opaque part numbers). Sometimes there are still schematics, Agisight still does it e.g. for low-end power supplies.
- ZenoArrow 9y agoYes, similar information used to be made available for Western electronics. In addition to engineering equipment, consumer electronics such as TVs and radios, and even computers had full schematics at one point. As an example, can see hardware schematics in the Apple II Reference Manual found here: http://www.applelogic.org/UserManuals.html http://www.applelogic.org/UserManuals.html I'm mostly interested in the Soviet material as I'm assuming that because it was a legal requirement the types of documented designs will be more broad, but if you know of an archive of old Western schematics also, I would be interested in taking a look.
